Merge tag 'memory-controller-drv-7.1' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into soc/drivers
Memory controller drivers for v7.1 1. TegraMC: - Few fixes for older issues - missing clock on Tegra264, missing enabling of DLL for Tegra30 and Tegra124. - Simplify the code in a few places. - Rework handling interrupts on different variants and add support for error logging on Tegra 264. 2. Drop Baikal SoC bt1-l2-ctl driver, because SoC support is being removed tree-wide. * tag 'memory-controller-drv-7.1' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: memory: tegra: Add MC error logging support for Tegra264 memory: tegra: Prepare for supporting multiple intmask registers memory: tegra: Group SoC specific fields memory: tegra: Add support for multiple IRQs memory: tegra: Group register and fields memory: tegra: Group error handling related registers memory: tegra-mc: Use %pe format memory: tegra-mc: Simplify printing PTR_ERR with dev_err_probe memory: tegra-mc: Drop tegra_mc_setup_latency_allowance() return value memory: renesas-rpc-if: Simplify printing PTR_ERR with dev_err_probe memory: brcmstb_memc: Expand LPDDR4 check to cover for LPDDR5 dt-bindings: cache: bt1-l2-ctl: Remove unused bindings memory: bt1-l2-ctl: Remove not-going-to-be-supported code for Baikal SoC memory: tegra30-emc: Fix dll_change check memory: tegra124-emc: Fix dll_change check memory: tegra: Add support for DBB clock on Tegra264 Signed-off-by: Arnd Bergmann <arnd@arndb.de>

-title: Baikal-T1 L2-cache Control Block
-
-maintainers:
- - Serge Semin <fancer.lancer@gmail.com>
-
-description: |
- By means of the System Controller Baikal-T1 SoC exposes a few settings to
- tune the MIPS P5600 CM2 L2 cache performance up. In particular it's possible
- to change the Tag, Data and Way-select RAM access latencies. Baikal-T1
- L2-cache controller block is responsible for the tuning. Its DT node is
- supposed to be a child of the system controller.
